(NOTE: do not be clever and configure a different database name, because it turns out that `wiki` is a baked-in default somewhere in vagrant's puppet scripts. Or, maybe in mediawiki's CLI scripts, but either way IT CANNOT BE OVERRIDDEN IN LocalSettings.php or DefaultSettings.php, or --conf, or the 'dbname-prefixname' CLI parameter. If you choose to change it, just know that it is a rabbit hole that will consume an hour of your life unproductively).

To install the Noisebridge.net wiki database on your MediaWiki-Vagrant instance, you will need to drop and recreate the MySQL database 'wiki' in order to eliminate the default MediaWiki 1.31 structure, to avoid problems overwriting it with our old MW 1.19 schema mysqldump

# Do this in VAGRANT_TERMINAL

$ mysql

> drop database wiki;

> create database wiki;

> ^D (that's a Control-D, as in hold down the Control key on your keyboard and strike the D key)
